Application Bled January 28, 19N. Serial No. 412,957.

To all whomr't may concern:

Be it known that I, JOHN FQLfovE, a citizen of the United States, residing at Zanesville, in the county of Muskingumand State of Ohio, have invented certain new and useful Im rovements in Valves; and I do declare t e following to bea f l, clear, and

exact description'of the invention,v such as will enable othersgiskilled in the art to whichV it a pertains to make and vuse the same.

T invention relates to improvements in automatically opening valves.

'Ihe object ofthe invention is to provide a valve of this character having means whereby the operating mechanism may be released from a distance and the valve thereby automatically opened.

A further object is to provide a valve of this character from which there will be positively no leakage'when the parts are in either an open or closed position.

With .these objects in view, the invention consists 4ol certain novel features of conL -structiemnombination and arra ment of artsvas he fully described anj articu arly pointed out in the a pendedc aims.

In the acompan ing rawings, Figure 1 is a vertical sect1ona view of the valve showing the arts in a closed position; and Fig. 2

is la simi ar view showing the parts in an open position; Fig. 3is a detail fra mentary sectionalview showing a modifie arrangement of the operating lever.

Referring more particularly to the drawy ing', 1 denotes the valve, which preferably consists oi a casing, comprising an u per section, 2, and a lower section', 3., `T e upper section, 2, is provided on its lower end wlth a reduced threaded projection which is adapted to be screwed into engagement with athreaded recess formed in the upper end of the-lower section. On the'lower section, 3, is formed a threaded nipple, 4, by means of which the valve is connected with thel object to which it is to be applied. In addition to 'the connection on the lowerv end of the section, 3, through `which the inlet passage, 5, of the valve is OImed, I provide on-one side of said section a laterally projecting connection, 6,-which may be in the form of aball joint for either a pipe or clamp connection and through this connection-is' formed the discharge passage, 7, of the valve. In the section 3 at the upper end of the inlet assage, 5, is formed a valve seat, 8, with W 'ch is adapted to be engaged a plunger valve, 9,

. ing the port, 5, as

said valve having formed thereon a radially projecting collar, 10, which is adapted to work in the recess in the section, 3, and to yform a fluid-tight joint with the upper end of said passage when the valve is in an open position.

The u per section, 2, of thevalve casing is provi ed with a recess or centrally disposed passage, 12 which is closed at its up.

per end by a plug, 13, through which is ormed a centrally disposed guide assage, 15, through which the stem, 16, of t e valve passes,-andis guided in its movements in the f The stem, 16, for a portion of its lengt in the recess, 12,` of the valve is threaded, as shown at '17, and on said threaded portion is ada ted to be screwed an operating nut, 18, w 'ch slides freely in the recess or passage, 12 of the upper section, 2, of the casing, and around said stem between the lower end of the nut, 18, and the lower .wall of the recess, 12 is arranged a coiled spring, 19, thepressure of. which is exerted to force the nut, 18, upwardly and thereby raise .the valve out of engagement with the seat 8 and thus open the inlet ort or discharge passage in the lower end o valve casing. The lower end of the spring \19 is preferably seated in a depression, 20,

forme inthe lower end of the recess, 12.I

The nut, 18, is held down and the valve, 9,

thereby held in closed osition by means oi a' lookin pin, 21, which 1s slidably mounted in a nipp e, 22, formed on one side of the upper section of the valve casing', as shown. The

.nipple 22 is provided with a recess or passage,

23 which communicates at its inner end with a reduced passage, 24, which opens into the recess, 12, in the valve casin The inner end of the locking pin, 21, is a apted to slide through the' reduced' passa e, 24, and to project int-o the recess, r12, an into engagement with a socket, 25, formed in one side of the nut and to thereby hold said nut down and the i again forced downwardly until the socket, 25,

`and between said collar and a cap, 28,

`inbefore described.

.screwed on the outer end of -the nipple, is

arranged a coiled spring, 29, thegresilienc'e of which is exerted to force the locking pin inwardl Pivotally connected. to the outer end o the locking pin, 21, is an operating le ver, 30, on the'inner end of which is formed a rlght-angularly projecting head, 31,v having a curved or segmental outer edge adapted to bear 1n a groove formed in the outer end of the cap, 28, whereby when the lever, 30, is pulled u Wardly, -said head, 31,` will bear yagainst t e end of the cap, and thereby draw the locking sin, 21 outwardly to disengage the inner en the nut, 18 thus releasing the latter and permitting the valve to o en 1n the manner heren the outer end of the lever, 30 is arranged a weight, 32, havin formed therein an aperture to which is tied an operating cord, 33, which may be extend-K' ed to any portion of the building whereby'the valve mav beoperated ata distance. vBy reversmg the lever, 30, on the end of the locking pin, 21 as shown in Fig. 3, said lever may be operated in a reverse directionby any suitable mechanism not shown.

By rov'iding' the collar, 10, on the stem of' the va ve, 9, in osition to e a e the u er end of the recesspformed in tli liwer secItibn of the valve casing,l any leakage of the valve when-in an open ositlon will be prevented'. On the u per en ran ed a sire to close the valve, the stem is turned by means'otthe wheel, thus screwin the nut, 18, downwardly and tightening' t e spring, 19, .until the loc socket, 25, 1s opposite to the end of the locking pin, at which time the sprin 29 will force said into the socket and t ereby hold the lnut down. I After the nut hasgthus been screwed down, the valve stem is. turned in, the o posite direction and thus screwed downwarry in the nut 18 until the valve 9 engages the seat, 8.
